WINDOW REGULATOR.

`applicati@sied Mai-eh s, 192e.l seriai no. 93,251.

The invention relates to window regulators and .isdesigned particularly for use in raising and loweringfthe windows of a railway car. The invention has for' some of its objects the provision of a window regulator which may beiiistalled in a railway car without changing tliecoiistruction of the latter; the provision of a window regulator having a crank which is so located thatrit does not interfere with the seating arrangement but is readily accessible for operation; theprovision of'a .dual window regulator having flifter arms for .independently raising and loweil'ing'the'inner and outer windows of a railway car; and the provision of means for raising and lowering a window screen respectievely upon lowering and` raisingk a window. 'lVith these as well as other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

lnthe drawings Figure l is an interior side elevation of a portion of a railway carl having `applied thereto a window regulator embodying niy invention; Y

Figure 2 is a similar view, enlarged kand partly broken away, to more clearly illustrate the invention;

Figures 3 and 4 are cross sections respectively on the lines 3--3 and lf-4 of Figure l; n

Figures 5 and6 are cross sections respectively on the lines 5`5 and 6-6 of Figure 2;

Figure 7 is a. diagrammatic vertical sectional elevation showing the manner of operating a window screen.

In general, and as vvshown particularly-in Figure l, a railway car such as 'a Pullman car has pairs of adjacent window openings with mirror panels l between the adjacent openings of the pairs and light panels 2 of considerably greater width than the mirror panels between the `pairs ofwindow openings. The widths o these lightpanels are sullicient to take care of the combined depths of the backs of the oppositely` facing seats 3. The light panels 2 each carry a pair of laterally spaced electric lights et and 5 which are located above the backs ofthe seats and may be separated by suitable partitions used in making up the berths. 6 are metallic channel-shaped Y upriglits opening toward each other and arranged in pairs, alternate pairs being located between the lpairs of window openings and the adjacent window openings of the pairs. 7 is the outer panel of the railway car andjS is apanel abovefthe light panels '2- and forming therewith the `inner panel of the railway car. These uprights with theinner and outer car 4panels form chambers abovethe window openings for receiving the windows when raised and also forni vertical chambers VVbetween `the pairs of window openingsof considerable.

cross sectional area which with` the 'chambers above the openings house the regulatorsfor operating tliewindows adjacent to and on opposite sides of the light panels. vThese window regulators, as shown, comprise lifter arms and mechanisms for actuating the` arms. n

Each window regulatoifis in the nature of a dual window regulator andlias the lifterarms 9 and l0 which extend within the` chambers above and at oneiside vof a window kopening laterally adjacent Va j light panel. The arms are'siiitably connected to theinner and outerwindows l1 andl, respectively, as by means ofthe angularly groovedlpins lupon the outer ends ofthe arms and theretainers 14 secured tothe upper edges of the windows. 'The points Jof engagement between the pins. and retainers are substantially in line with the vertical median. planes of the windows. 'The arms 94 and l0 extend through the openings 15 locatedin the web of the upright 6 and are pivotally mounted upon` ,theniounting plate 1,6 which is secured to the web and has the h'ub 18, at the 'opposite ends of .which the arms are mounted. 17 is the pin extending through the arins and hub for pivotally connecting the same. The 'distances between the inner ends of the arms and their pivots are less thanone-half the .width of the chamber laterally adjacent to the window opening so Athat the arms of one vdual window reguli-itor.can not interfere l with .the arms of the other dual Lwindow regulator making use of the same chamber between the window openings.

' For swinging the lifter arms to raise-and lower the .windows which are .connected thereto, I have provided the racks y19j and120 which` extend upwardly within thel chamber at ythe side of the windowopening and are lit pivotally connected at their upper ends to the inner ends ot the lifter arms t) and lt), respectively. The teeth et these racks tace toward each other and respectively mesh with the lower and upper pinions 2l and 22 on opposite sides ol the plane extending through and parallel with the axes of these pinions. The racks 19 and '2O are held'in mesh with their pinions 2l and 22, respectively, by suitable means such as the lower and upper rolls i223 and Qi, respectively, which enffage the backs ot the racks. rlhe pinions and the acksare so arranged that during the swinging of the litter arms` and also the more limited swinging ot the racks. neither rack can come into engagementl with the pinion tor driving the other rack.

'lhe rolls and the means for rotating the pinions are carried by a mounting which is so positioned that the cranks ot the pinion actuating means are preferably located below the electric lights upon the light panels 2. As shown, the mounting comprises the vertically extending channel Q5 having toot flanges 2G extending toward each other and rigidly secured to the outer ear panel T by suitable means such as the bolts QT and nuts QS. 29 is aY second vertically extending channel which is located within the channel and has its web laterally spaced. trom the web of the last-mentioned channel. The rolls Q3 and i24- have reduced ends which are journaled in these laterally spaced webs ot the channels. The pinions 2l and 22 are intcrchangeable and as shown are elongated and have outer reduced ends journaled in the web of the channel Q9 and inner ends extending through and journaled upon the web ot the channel Q5. 3l are drive shafts suitably connected to the pinions by irreversible drive mechanism located within the cups 30 which are rigidly secured to the inner sides of the webs of the channels 25. The inner ends of the pinions and the outer ends oit the shafts are preferably jouriraled in these cups. The shafts 3l extend reely through the light panels 2 below the electric lights carried by these panels and have lixedly secured to their inner ends the cranks rlfhe light panels Q are provided with the inwardly extending embossed portions 2 through which the shafts ill extend. These embossed portions form eseuteheons against the inner laces ot which the cranks abut. Furthermore, these embossed portions form bearing for the hubs 32' ot the cranks and consequently rotatably support the inner ends of the shafts 231.

For the purpose ot guiding the racks, the rolls 23 and 2l are preferably provided with annular grooves 33 in which the backs of the racks engage. These rolls are also preferably made to be interchangeable.

F or the purpose of countcrbalancing the weights ot the windows, I have provided the tension coil springs 3l, which are connected to the lower ends olf the racks l?) and 2t) and to the frame of the railway car at the lower end of the chamber between the pairs ot window openings.

The windows ll and 12 are of the sashless type to accommodate the litter arms and the window screen which is adapted to ex tend between these windows. Ilt are vertical guideways formed olf librous material such as telt and having parallel grooves cut. therein lor engagement with the windows and screen. 'lhese guideways are secured against the webs of the uprights G and lorm weather seals between the edges ot the windows and the uprights. 3T is a yieldable abutment preleral'ily formed of rubber mounted upon the sill 35i at the bottom of each window opening. rflis abutment is ..:ecured to the. sill by means` ot' the stool fit) which has the recess slt) l'or receivingr the bead il upon the inner edge of the :butment. 'l`he abutment has the coneavities l2 in its upper 'tace providing the shoulders l-l 1for engagement with the windows. and screen, so thatA the alnitment is adapted to lorm a weather sail between the lower edges. ot the windows and the sill.

The screen is raised and lowered upon movement of one of the windows7 which in the present instance is the inner window ll. Furthermore, the screen is norinally concealcd in the chamber above the window opening when the inner windev.' is in its lowermost position. The connection between the screen and the inner windows cone prises cables` ll located to lie within the grooves formed in the guideways 36, each cable having one end secured lvnetierahly to the inner panel above the, opening and the other end secured to the upper edge of the screen, intermediate portions ol the cable passing over the pulley l5 upon the upper edge olf the inner widow and also the pulley l() preferably secured to the inner' panel of the ear. Vv'ith this arrangement, the screen has twice the travel of the inner window so that when the latter raised to its l'ull open position, at which time its lower edge occupies a position vertically midway olf the opening, the screen is completelv lowered to rest upon the yieldable abutment 2.57.
